Scheduling Policies for Differentiated Services in the Internet

Gunter Bolch, University of Erlangen, Germany

Priorities, and recently specially time dependent priorities,
are used to improve the QoS of the Internet.
In the first part of the talk analytical methods to determine
QoS parameters as throughput or delay times in time independent
and time dependent priority systems are introduced.
These methods are used in the second part of the talk to
obtain QoS parameters of the "Proportional Differentiated
Service Archicture" of the internet.
In this architecture time dependent priorities are used to
achieve a given delay ratio between the traffic
classes in the routers of the internet. Using the analytical
results it is shown that the given delay ratio is met under
heavy load conditions and a new method is introduced to meet
the given delay ratio also under medium load conditions.
